Free Nursing 612 API Adult Gerontology at St Thomas University Questions
In the initial screening for a diagnosis of AAA, which of the following is the best screening test?
-
Ultrasound in the abdominal area
-
Complete blood count (CBC)
-
Angiography
-
CT scan
Explanation
The Correct Answer is:
A. Ultrasound in the abdominal area.
Detailed Explanation:
Abdominal ultrasound is the preferred initial screening test for an abdominal aortic aneurysm (AAA) because it is noninvasive, safe, inexpensive, and highly accurate in detecting the presence and size of an aneurysm. It allows visualization of the aorta and precise measurement of its diameter.
While a CT scan provides detailed anatomical information and is used for preoperative evaluation or when rupture is suspected, it is not the first-line screening tool. Angiography is invasive and used for surgical planning, and a CBC is not diagnostic for AAA. Therefore, abdominal ultrasound is the best choice for initial detection and population screening, especially in older adults and smokers.
Treatment to slow the progression of PAD should include which of the following? Select all that apply.
-
Conservative
-
Surgical
-
Pharmacological
-
Heat
-
Immobilization
Explanation
The Correct Answers are:
A. Conservative, B. Surgical, and C. Pharmacological.
Detailed Explanations:
A. Conservative:
Conservative management is the first-line approach for peripheral arterial disease (PAD). It includes lifestyle modifications such as smoking cessation, regular exercise (especially walking programs), weight control, and a heart-healthy diet. These interventions improve circulation and slow disease progression.
B. Surgical:
Surgical or interventional procedures, such as angioplasty, stent placement, or bypass grafting, are used in severe cases to restore adequate blood flow when conservative and medical therapies are insufficient.
C. Pharmacological:
Medications such as antiplatelet agents (aspirin or clopidogrel), statins, and cilostazol help improve blood flow, prevent clot formation, and reduce atherosclerotic progression.
Which of the following conditions is signaled by symptoms of swelling of the affected body part, usually the limb, because of impaired flow of lymph fluid?
-
Abdominal aortic aneurysm (AAA)
-
Peripheral vascular disease (PVD)
-
Lymphedema
-
Venous ulcers
Explanation
The Correct Answer is:
C. Lymphedema.
Detailed Explanation:
Lymphedema is a chronic condition characterized by swelling—most often in the arms or legs—due to impaired lymphatic drainage. It occurs when lymph fluid cannot properly circulate and accumulates in the tissues. The swelling is typically firm, non-pitting, and may progress over time, causing discomfort, skin thickening, and reduced mobility.
In treating AAA, arterial monitoring is recommended. Which of the following IV antihypertensive agents should be used to rapidly and consistently maintain blood pressure in the mean arterial pressure ranges? Select all that apply.
-
Esmolol
-
Carbidopa
-
Nitroglycerin
-
Nicardipine
-
Sertraline
Explanation
The Correct Answers are:
A. Esmolol and D. Nicardipine.
Detailed Explanations:
A. Esmolol:
Esmolol is a short-acting beta-blocker that provides rapid and precise blood pressure control. It is particularly useful in patients with aortic aneurysm because it reduces heart rate and myocardial contractility, lowering shear stress on the aortic wall and minimizing the risk of rupture.
D. Nicardipine:
Nicardipine is a calcium channel blocker administered intravenously for smooth, titratable control of hypertension. It effectively lowers blood pressure without compromising organ perfusion, making it ideal for managing blood pressure in acute aortic conditions such as an abdominal aortic aneurysm (AAA).
In the assessment for peripheral vascular disorders, the clinician should begin with which of the following after the general history and physical examination?
-
Palpation of the carotid arteries bilaterally.
-
Order diagnostic testing.
-
Auscultation of the carotid arteries bilaterally.
-
Inspection of the carotid arteries bilaterally.
Explanation
The Correct Answer is:
C. Auscultation of the carotid arteries bilaterally.
Detailed Explanation:
After completing the general history and physical examination, the clinician should auscultate the carotid arteries bilaterally before palpation. This helps detect the presence of a carotid bruit, which indicates turbulent blood flow often caused by atherosclerotic narrowing or stenosis. Palpating the carotid arteries before auscultation can dislodge plaque and potentially cause embolization leading to stroke. Therefore, auscultation is the safest and most appropriate first step when assessing for peripheral vascular disorders involving the carotid arteries.
Sam is 64 years old and has been feeling weak, lightheaded, and slightly nauseous. He goes to the urgent care center where the nurse practitioner initiates an assessment. Which of the following suggest an arrhythmia? Select all that apply.
-
Palpitations and syncope.
-
Chest x-ray showing an increased size of the left atria.
-
Lack of family history of any acute heart conditions.
-
History of alcohol drinking.
-
No history of heart pounding, racing, or skipping beats.
Explanation
The Correct Answers are:
A. Palpitations and syncope and D. History of alcohol drinking.
Detailed Explanations:
A. Palpitations and syncope:
These are classic symptoms of an arrhythmia. Palpitations indicate an irregular or rapid heart rhythm, and syncope (fainting) can occur when the arrhythmia reduces cardiac output, causing transient cerebral hypoperfusion.
D. History of alcohol drinking:
Chronic or excessive alcohol intake, sometimes called “holiday heart syndrome,” can trigger atrial fibrillation or other arrhythmias. Alcohol affects cardiac conduction and electrolyte balance, increasing the likelihood of rhythm disturbances.
Devon visits the urgent care facility for sudden symptoms of pain to his lower extremity. The initial diagnosis is acute arterial ischemia. Aside from pain, which other symptoms may arise from this diagnosis? Select all that apply.
-
Paresthesia
-
Pulselessness
-
Purulence
-
Paralysis
-
Pallor
Explanation
The Correct Answers are:
A. Paresthesia, B. Pulselessness, D. Paralysis, and E. Pallor.
Detailed Explanations:
A. Paresthesia:
A tingling or numb sensation occurs due to reduced blood flow and oxygen supply to peripheral nerves, an early sign of ischemia.
B. Pulselessness:
Absent or diminished peripheral pulses indicate a severe reduction or total loss of arterial blood flow, a hallmark sign of acute arterial occlusion.
D. Paralysis:
Muscle weakness or inability to move the affected limb may develop as ischemia progresses and nerve and muscle tissues become deprived of oxygen.
E. Pallor:
The affected limb appears pale or ashen due to lack of arterial perfusion. This can progress to mottling and cyanosis if circulation is not restored.
The nurse practitioner and a student are examining the apical pulse of an 82-year-old man. The student perceives that there is an S4 sound. The nurse practitioner interprets that this is likely:
-
Mitral regurgitation.
-
Normal, due to the man's age.
-
Heart blockage
-
An early ventricular filling.
Explanation
The Correct Answer is:
B. Normal, due to the man's age.
Detailed Explanation:
An S4 heart sound (also called an atrial gallop) occurs just before S1 and results from the atria contracting forcefully to overcome decreased ventricular compliance. This is common in older adults due to age-related stiffening of the ventricular wall or mild diastolic dysfunction. In an elderly person without other signs of heart failure, an S4 is often considered a normal age-related finding.
Mr. Borden is 79 years old and lives with his daughter. The daughter provides excellent care for her father and wants to know which changes in his heart and circulatory system are due to aging and which are due to lifestyle choices. The nurse practitioner replies:
-
The size of the heart increases with age.
-
The activity of the heart decreases in its ability to deal with stress, as well as to provide physical strength as one ages.
-
The left ventricle hypertrophies in response to increasing in age.
-
The patient’s diet affects the ability of the heart to balance blood pressure.
Explanation
The Correct Answer is:
B. The activity of the heart decreases in its ability to deal with stress, as well as to provide physical strength as one ages.
Detailed Explanation:
With normal aging, the cardiac reserve—the heart’s ability to increase output during stress, illness, or physical exertion—declines. This occurs due to decreased myocardial contractility, reduced responsiveness to catecholamines, and increased stiffness of the myocardium and arteries. As a result, older adults experience reduced tolerance for activity and slower recovery from physical or emotional stress. This diminished function is a natural part of aging, not necessarily caused by poor health habits.
The nurse practitioner sees a patient in the emergency department with reports of chest pain and nausea. To analyze the patient’s condition, what further information is needed?
-
Whether there has been constipation.
-
Information regarding last food intake.
-
Information regarding urinary difficulties.
-
A description of the pain.
Explanation
The Correct Answer is:
D. A description of the pain.
Detailed Explanation:
When a patient presents with chest pain and nausea, obtaining a detailed description of the pain is essential for determining whether it is cardiac in origin. The nurse practitioner should assess the location, quality, duration, intensity, radiation, and precipitating or relieving factors of the pain. This helps differentiate cardiac ischemia (e.g., angina or myocardial infarction) from gastrointestinal, musculoskeletal, or pulmonary causes. While food intake or bowel/urinary issues may provide supporting clues, the pain characteristics are the most critical diagnostic component for immediate assessment and intervention.
